TEA1833LTS/1X

The TEA1833LTS/1X is an offline switcher designed by NXP Semiconductors, offering an efficient and cost-effective solution to power critical components in a variety of applications. The TEA1833LTS/1X is housed within a TO-220 package, making it suitable for a wide range of PCB designs, including those with limited space.

The TEA1833LTS/1X is a single step AC-DC converter that is used to supply power to trusted systems, mixed signal circuit protection, and EMI circuits, as well as for powering embedded and wireless applications. It is highly efficient, providing up to 92% efficiency at half-load, and supports a wide input voltage range from 85 VAC to 250 VAC.

The TEA1833LTS/1X features a built-in thermal protection circuit, enabling it to safely operate in temperatures between -25°C and +125°C. Its output power and integral EMI filter meet FCC and EN standards, enabling it to pass safety and reliability tests with ease. It also supports full-wave rectification and has a built-in switch with overcurrent, overvoltage, and over-temperature protection.

The TEA1833LTS/1X\'s working principle is simple. It uses a single step AC-DC converter to convert the AC input voltage of 110–250 V to a DC output of 3.3 V. It consists of an NCT1008 topology, which uses a linear regulator to provide high accuracy with low power dissipation. An integrated totem pole driver is used to control the switching frequency and to provide an internal soft-start. The built-in switch is used to reduce the switching noise, while a timer circuit is used to control the on-time of the switch and thus to regulate the output power.

The TEA1833LTS/1X is an ideal solution for providing power to embedded systems, wireless communications devices, and smart meters. It is also suitable for use in medical, gaming, and industrial applications where power efficiency and reliability are paramount. Thanks to its small size, high efficiency, and thermal protection features, the TEA1833LTS/1X offers an attractive solution for designers looking for an efficient and cost-effective offline switcher.
